Abstract

An impeller (10) includes: a boss section (11, 111) having a columnar contour; and a plurality of rotary blades (12, 112) mounted to the boss section (11, 111) in a radiate manner. Each of the plurality of rotary blades (12, 112) includes a first region (AR1) extending from an inner peripheral edge (12c, 112c) connected to the boss section (11, 111) to a predetermined radial position (Rd) to have a first stagger angle distribution (D?. D?1, D?11), and a second region (AR2) extending from the predetermined radial position (Rd) adjacent to the first region (AR1) to an outer peripheral edge (12d, 112d) to have a second stagger angle distribution (D?2) being different from the first stagger angle distribution (D?. D?1, D?11). The second stagger angle distribution (D?2) includes a distribution in which a stagger angle (?) decreases from a maximum radial position (Rmax), at which the stagger angle (?) is maximum in the second region (AR2), toward the outer peripheral edge (12d, 112d). FIG. 2.
